Kinematics Diagrams
Our topics today: • Describing Motion with Diagrams • Stroboscopic Images • Vector Diagrams • x-t, v-t, a-t graphs • Motion in constant acceleration • 1D Kinematic Equations • That’s it, folks!
Stroboscopic Images time 1 sec 2 sec 3 sec position 1 cm 5 cm 11 cm
Stroboscopic images • Try daw ang interactive physics. ;)
Vector Diagrams Using Displacement Vectors
Displacement-time (x-t) graphs • Which is which? • Positive and changing velocity (acceleration) • Positive and constant velocity A B Get 1/4
Displacement-time (x-t) graphs Which is which? 3. Slow, leftward (-), Constant Velocity 4. Fast, leftward (-), Constant velocity 5. Slow, rightward (+), constant velocity 6. Fast, rightward (+), constant velocity A B C D
Displacement-time (x-t) graphs Which is which? 7. Negative velocity (-), slow to fast 8. Leftward velocity (-), fast to slow A B
Velocity-time (v-t) graphs Constant Velocity Changing Velocity, Constant Acceleration
Velocity-time (v-t) graphs The area bounded by the “curve” and the x-axis determines the displacement, or how far the ball travels.
Motion in Constant Acceleration • That’s something for the black board. • Reminder: Quiz Next Meeting • Vectors • Vector properties • Resolving vectors into x- and y- components • Numerical addition of vectors • Et cetera
